In this article, we will discuss the concept of the C++ code to sum of two integer using Bitwise operator
In this post, we are going to learn how to write a program to find the sum of two numbers using Bitwise operator in C++ programming language
The program allows the user to enter two integers and then calculates sum of given numbers using Bitwise operator in C++ language
Program 1
#include <iostream> #include <conio.h> using namespace std; int main() { int a,b,num1,num2; cout<<"Enter the first number: \n"; cin>>num1; //Ask the number from the user for num1 cout<<"Enter the second number: \n"; cin>>num2; //Ask the number from the user for num2 a=num1;//Assign the value of num1 to a b=num2;//Assign the value of num2 to b while (num2!= 0) {//Calculate the sum of two numbers using bitwise operator int count=num1 & num2; num1=num1^num2; num2=count<<1; } cout<<"Sum of two numbers "<<a<<" and "<<b<<" is: "<<num1; //Display output on the screen getch(); return 0; }
When the above code is executed, it produces the following result
Enter the first number: 200 Enter the second number: 300 Sum of two numbers 200 and 300 is: 500
The program allows the user to enter two integers and then calculates sum of given numbers using Bitwise operator in C++ language
Program 2
#include <conio.h> using namespace std; int sub(int,int); int main() { int num1,num2,ans; cout<<"Enter two numbers: \n"; cin>>num1>>num2; //Ask input two integers and store the variables num1,num2 ans=sub(num1,num2);//Calling the function //and assign the output to variable ans cout<<"Sum of "<<num1<<" and "<<num2<<" is "<<ans; getch(); return 0; } int sub(int x, int y){//function definition while(y!=0){//Calculate the sum of two numbers using bitwise operator int carry=x & y; x=x^y; y=carry<<1; } return x; }
When the above code is executed, it produces the following result
Enter two numbers 125 375 Sum of 125 and 375 is: 500
